At this time, in the normal state in which the bottom surface 352 of the leg part 13 of the aforementioned apparatus main body 11 is in contact with the mounting surface 351, and the operation part 342 of the aforementioned stand switch 293 is pushed by the aforementioned mounting surface 351 and is retreated, the aforementioned stand switch 293 is on, and the input port 291 of the microcomputer 201 to which the stand switch 293 is connected is kept “L”, whereas when the apparatus main body 11 falls down, the bottom surface 352 of the leg part 13 of the apparatus main body 11 separates from the mounting surface 351 and the operation part 342 of the aforementioned stand switch 293 is extended, the stand switch 293 is operated to be turned off, and the aforementioned input port 291 changes to “H” from “L”.
Therefore, when the aforementioned stand switch 293 is operated to be turned off, and the input port 291 of the microcomputer 201 changes to “H” from “L”, it can be detected that the apparatus main body 11 falls down based on the off operation of the aforementioned stand switch 293, and therefore, the flow branches to step S6.
In step S6, it is determined whether or not the aforementioned bottle switch 303 is operated to be turned on (S6).
Here, when the spray can 51 is set in the housing space 52 of the aforementioned apparatus main body 11, and the can main body 55 of the spray can 51 presses the operation part 332 of the aforementioned bottle switch 303 and is retreated, the aforementioned bottle switch 303 is configured to be turned on so that the input port 301 of the aforementioned microcomputer 201 becomes “L”. When the spray can 51 is not set in the aforementioned housing space 52, and the operation part 332 of the aforementioned bottle switch 303 is extended to the aforementioned housing space 52 side, the aforementioned bottle switch 303 is configured to be turned off so that the aforementioned input port 301 becomes “H”. Thereby, the set state of the aforementioned spray can 51 in the aforementioned housing space 52 is configured to be detectable.
Therefore, when the aforementioned input port 301 is “H”, and the aforementioned spray can 51 is not set in the aforementioned housing space 52, the flow branches to the aforementioned step S1 and returns to the initial state, whereas when the aforementioned input port 301 is “L”, and the aforementioned spray can 51 is set in the aforementioned housing space 52, the flow shifts to the aforementioned step S5, and until the apparatus main body 11 which falls down is raised, and the aforementioned stand switch 303 operates, the flow enters the loop of steps S5 and S6.
Meanwhile, when in the aforementioned step S5, the aforementioned input port 291 is “L”, and it can be confirmed that the apparatus main body 11 stands upright on the aforementioned mounting surface 351, it is determined whether or not the aforementioned bottle switch 303 is operated to be turned on (S7).
At this time, if the aforementioned input port 301 is “H”, and the aforementioned spray can 51 is not set in the aforementioned housing space 52, the flow branches to the aforementioned step S1 and returns to the initial state, whereas if the aforementioned input port 301 is “L” and the aforementioned spray can 51 is set in the aforementioned housing space 52, the flow shifts to the next step S8.
In this step S8, it is determined whether or not the aforementioned eject time during countdown becomes “0” and the time is up (S8), and when the time is up, the flow shifts to step S10, whereas when the time is not up, the flow branches to step S9, and it is determined whether or not the turbo button 363 of the top part 61 of the aforementioned apparatus main body 11 is pressed (S9).
At this time, in the off state of the aforementioned turbo switch 283 in which the turbo button 363 in the top part 61 of the aforementioned apparatus main body 11 is not pressed, and the operation part 362 of the aforementioned turbo switch 283 is extended, the input port 281 of the aforementioned microcomputer 201 becomes “H”, whereas when the aforementioned turbo button 363 is pressed down, the operation part 362 of the aforementioned turbo switch 283 retreats and the turbo switch 283 is operated to be turned on, the input port 281 of the aforementioned microcomputer 201 changes to “L” from “H”.
Therefore, when the aforementioned input port 281 is “L”, and the aforementioned turbo switch 283 is operated, the flow shifts to the aforementioned step S10 and the spray process is performed, whereas when the aforementioned input port 281 is “H” and the aforementioned turbo switch 283 is not operated, the flow branches to the aforementioned step S3 and the aforementioned respective steps are repeated until the aforementioned eject time which is being counted down is up.
In the aforementioned step S10, “H” is outputted from the output port 242 of the aforementioned microcomputer 201 for a predetermined time which is set in advance, and the NPN transistor 233 and the PNP transistor 216 are operated to be turned on, whereby, the power from the aforementioned power supply 211 is supplied to the aforementioned drive motor 73. Subsequently, the drive motor 73 rotates the cam 92 via the aforementioned respective reduction gears 83 to 86 of the spray mechanism 96, and the lever 94 supported by the rotating shaft 93 is tilted by the cam 92, whereby the spray adapter 57 of the spray can 51 is pressed downward, and the agent is sprayed from the spray can 51 (S10).
Subsequently, “1” is added to the aforementioned total spray counter secured in the aforementioned RAM (S11), the aforementioned timer value stored in the aforementioned eject timer value based on the slide state of the aforementioned slide switch 271 is set again to the aforementioned eject time (S12), after which, it is determined whether or not the aforementioned total spray counter reaches “1400” (S13).
Since at the initial stage, the aforementioned total spray counter does not reach “1400”, the flow shifts to the aforementioned step S3 and spray of the agent is repeated at each time indicated by the aforementioned timer value, whereas when the aforementioned total spray counter reaches “1400” and spray of the aforementioned agent is performed 1400 times, it is determined whether or not the spray can 51 set in the aforementioned housing space 52 is replaced, from the presence or absence of the state change of the aforementioned bottle switch 303 (S14). After the flow waits until the spray can 51 is replaced, and when the spray can 51 is replaced, the flow branches to the aforementioned step S1 and returns to the initial state.
Like this, when the apparatus main body 11 falls down while the apparatus main body 11 in which the aforementioned spray can 51 is set is mounted on the mounting surface 351 and used, it can be detected that the aforementioned apparatus main body 11 falls down in step S5 of determining the state of the aforementioned stand switch 293, and when a fall of the apparatus main body 11 is detected, the flow branches to the aforementioned step S6 and enters a loop, whereby, a shift to the spray process of the aforementioned step S10 of spraying the agent from the aforementioned spray can 51 can be avoided.
As a result, if the aforementioned apparatus main body 11 falls down, spray of the agent from the aforementioned spray can 51 can be prevented.
Therefore, even if the spray apparatus 1 falls down, spray of the agent in an unintended direction can be prevented, as compared with the conventional spray apparatus which sprays an agent when the spray requirements such as a lapse of a predetermined time, and operation of the spray switch are fulfilled.
Thereby, for example, even if the apparatus main body 11 falls down with the spray port 63 of the top part 61 facing the wall surface, the trouble which can occur at the time of falling that the agent is sprayed to the wall surface and contaminates the wall surface can be reliably prevented.
When the apparatus main body 11 is lifted up and transferred, spray of the aforementioned agent can be prevented, and therefore, the troubles due to spray of the agent to hands and legs, clothes and the like can be reliably prevented.
Even if the aforementioned turbo button 363 is mistakenly pushed during the transfer, by entering the loop of the aforementioned steps S5 and S6, spray of the aforementioned agent can be prevented, and therefore, the trouble due to spray of the agent by a malfunction during the transfer can be avoided.
Further, the aforementioned apparatus main body 11 is provided with the stand switch 293 as the bottom surface switch which operates when the bottom surface 352 of the leg part 13 of the apparatus main body 11 separates from the mounting surface 351, and a fall of the aforementioned apparatus main body 11 can be detected from the operation state of the stand switch 293.
Therefore, as compared with the case of using an expensive inclination sensor which detects the inclination of the aforementioned apparatus main body 11, a measurement sensor which measures a separation distance from the aforementioned mounting surface 351 and detects separation from the mounting surface 351 and the like, cost can be reduced, and the configuration can be simplified.
Meanwhile, the top part 61 of the aforementioned apparatus main body 11 is provided with the turbo switch 283 as a push-button type spray switch, and by operating the turbo switch 283 by depressing the turbo button 363 of the turbo switch 283, in the aforementioned step S9, the flow is forcefully branched to the spray process of the aforementioned step S10, and the aforementioned spray process is executed, so that the aforementioned agent can be sprayed.
Therefore, as compared with the case in which the apparatus has to wait for spray of the agent until the next spray time comes, the use mode can be enlarged, and the convenience is enhanced.
At this time, the aforementioned apparatus main body 11 is formed in a laterally oriented shape in plane view, and at the right side in FIG. 4 with the center in the lateral direction of the apparatus main body 11 as the boundary, the aforementioned stand switch 293 as the aforementioned bottom surface switch and the aforementioned turbo switch 283 which is the aforementioned spray switch are disposed. Therefore, in the state in which the turbo button 363 of the aforementioned turbo switch 283 provided in the top part 61 of the aforementioned apparatus main body 11 is operated by being depressed, an accidental lift at the right side in FIG. 4 of the bottom surface 352 of the aforementioned leg part 13 where the aforementioned stand switch 293 is provided can be prevented.
As a result, as compared with the case in which the right side in FIG. 4 of the aforementioned bottom surface 352 where the aforementioned stand switch 293 is provided is lifted when the turbo button 363 of the aforementioned turbo switch 283 is operated by being depressed, an accidental operation of the aforementioned stand switch 293 at the time of depressing the aforementioned turbo button 363 can be prevented.
Thereby, an accidental operation of the spray preventing function of the aforementioned agent due to the state change of the stand switch 293 can be prevented.
In the present embodiment, only the case of detecting a fall of the apparatus main body 11 by the aforementioned stand switch 293 is described, but the present invention is not limited to this.
For example, the present invention may be configured by using, for example, an inclination sensor which detects the inclination of the aforementioned apparatus main body 11, a measurement sensor which measures a separation distance from the aforementioned mounting surface 351 and detects separation from the mounting surface 351, and the like.
Further, in the present embodiment, the case in which the state of mounting the aforementioned apparatus main body 11 on the aforementioned mounting surface 351 is set as a proper position is described, but the present invention is not limited to this.
For example, the state in which the apparatus main body 11 stands upright along the wall surface of a room, and the state of hanging the apparatus main body 11 on the aforementioned wall surface can be set as the proper positions.
In this case, by providing the switch which operates when the rear surface separates from the opposing surface to which the rear surface being one surface of the aforementioned apparatus main body 11 is opposed, it can be detected that the aforementioned apparatus main body 11 is not installed in the aforementioned proper position from the operation state of the switch.
Further, in the present embodiment, the case is described as an example, in which the spray port 63 from which the aforementioned agent is sprayed is provided to face up in the top part 61 of the apparatus main body 11 and the agent is sprayed to right above, but the present invention is not limited to this.
For example, the spray apparatus 1 which sprays an agent diagonally upward, or sprays the agent forward may be adopted.
